Agriculture is the foundation of the economy in Sri Lanka. Presently, many factors affect agriculture production leading to crop losses and food waste in Sri Lanka. An in-depth study of these factors exposed that the root causes were the improper agricultural practices followed by the farmers and inaccessibility to the required information at the right time for optimal decision-making. As a solution, earlier, a mobile-based application called "Govi Nena" was developed for farmers in Sri Lanka. In this work, we have extended the earlier version of the application to suit the different needs of farmers. This extension includes delivering the required information similar to how the information is delivered in GIS and a new module for farmers to manage real-time pest/disease incidences. Finally, the prototyped version of the application was tested among several farmers in Sri Lanka to understand the suitability of the work concerning farmers' requirements.
